Hex Logic Level Down Converter
General Descript ion
The MM74HC4049 and the MM74HC4050 utilize
advanced silicon-gate CMOS technology, and have a mod-
ified input protection structure that enables these parts to
be used as logic level translators which will convert high
level logic to a low level logic while operating from th e low
logic supply. For example , 0–1 5V CMOS log ic can be con-
verted to 0–5 V logi c whe n usin g a 5V su pply. The modified
input protection has no diode connected to VCC, thus allow-
ing the input voltage to exceed the supply. The lower zener
diode protects the input from both positive and negative
static voltages. In addition each part can be used as a sim-
ple buffer or inverter without level translation. The
MM74HC4049 is pin and functionally compatible to the
CD4049BC and the MM74HC4050 is compatible to the
CD4050BC

Note 4: F or a power supply of 5V ±10% the wor st case output vo ltages (VOH and VOL) occur f or HC at 4.5 V. Thus th e 4.5V values should be u sed wh en
designing with this supply. Worst case VIH and VIL occur at VCC = 5.5 V and 4. 5V respec t iv ely. (The VIH value at 5. 5V is 3.85V.) The wors t c as e leaka ge cur-
rent (IIN, ICC, IOZ) occur fo r C M OS at the higher volt age and so the 6.0V values sh ould be us ed.
